. UNDERLIFT- FOR RULING PENS.

Application filed July 2, 1925. Serial No. 41,159.

The present invention relates to means for engaging the ruling pens of a ruling machine to raise the same from the paper, said means being lifts.

The object is to provide a simple device for the purpose that can be readily positioned with respect to a pen and is easily adjustable to effect the desired lifting action.

In the accompanying drawing.

Figure 1 is a detail perspective view of a portion of a ruling machine illustrating two of the underlifting devices in associated relation to the pens.

Figure 2 is a sectional view through the rock shaft for the underlift devices, and a side elevation of one of said devices detached from the shaft.

In the structure as disclosed, a portion of a pen beam is indicated in outline at 3, and

carries a plurality of pens, shown at 4:. Operating beneath the pen beam and pens is the usual sheet conveyor in the form of a belt or cloth 5. These parts are well-known, and it is believed unnecessary to go into further detail regarding them. Located below the pens l is a rock shaft 6 that is angular in cross section, and may have one of its faces roughened or knurled, as illustrated at 7. On th s shaft are located the underlift devices. These devices each consists preferably of a single piece of sheet metal having some resilience, as for example, spring brass. The strip has one end portion formed into an angular loop or open collar 8. The open side is preferably of less width than the shaft 6; the other end of the strip extends outwardly from the loop and constitutes a pen-engaging arm or finger 9.

In us ng the underlift, the loop is sprung upon the shaft 6 and frictionally engages the same, the arm outstanding beneath the pen, as illustrated in Figure 1. This arm may be readily bent to position, so that when the shaft is turned in one direction, it will engage the free end of the pen and lift it from the paper, and when the shaft is turned generally known as under-' in the opposite direction it will disengage the pen and allow it to rest upon the paper. Obviously these underlift devices can be cheaply manufactured and may be readily placed in any desired position on the shaft, being slidable along the same to any point desired.

From the foregoing, it is thought that the construction, operation and many advantages of the herein described invention will be apparent to those skilled in the art, with out further description, and it will be understood that various changes in the size, shape, proportion and minor details of construction may be resorted to without departing from the spirit or sacrificing any of the advantages of the invention.

What I claim, is:

1. An underlift for ruling pens comprising a rock shaft with flat faces, and a penengaging arm having a collar portion that embraces the shaft and provided with sub stantially flat faces that bear against the flat faces of the rock shaft.

2. An underlift for ruling pens comprising a rock shaft that is angular in cross section, and a pen-engaging arm having a collar portion that is angular in form and embraces the shaft.

3. An underlift for ruling pens comprising a rock shaft having a substantially flat roughened face, and a pen-ei'igaging arm having a collar port on that embraces the shaft and is slidable thereon, said collar portion bearing against and being held against accidental displacement by the roughened portion.

4. An underlift for ruling pens comprising a rock shaft that is angular in cross sec tion and has one of its fiat faces roughened, and a pen-engaging arm having an angular collar portion that embraces the shaft and has a substantially flatside bearing against the flat roughened'face of the rock shaft.

In testimony whereof, I afliX my signature.
